If you have an SXGA+ (1400x1050) screen, you have to use this size instead of 1024x768, and you have to set DefaultDepth to 16 to use AIGLX because of the limited graphics memory.

Revision as of 13:13, 22 October 2008


Installation

Works with no known issues. The point releases "Voodoo" and "Don't Panic" work without problems.

Configuration

Power Management

Suspend and Hibernate

Works flawlessly. See Suspend to Disk. Also known to work with Pm-utils.

Laptop Mode Tools

Works flawlessly. See Laptop Mode Tools.

CPU Frequency Scaling

Works as described in CPU Frequency Scaling with acpi-cpufreq as of 2.6.27-ARCH. Maybe you need to use speedstep-ich on earlier kernels.

Hotkeys

They work better after loading the thinkpad-acpi module, to assign the generated keycodes to there supposed functions.

As of December 2007, they don't work properly, since HAL is messing around with it's improvements. Read further in the Troubleshooting section.

tpb

tpb (for Thinkpad Buttons) is available through pacman:

pacman -S tpb 

tpb adds an on-screen volume bar for the volume buttons, THINKPAD button assignment, on-screen messages for Thinklight, (on and off) and more.

NumLk

Yes, this didn't work from the beginning for me, but here is the solution:

keycode 77 = Num_Lock 

Add that line to your ~/.xmodmap file.


Xorg

Works with driver xf86-video-savage.

Here is the mentioned file, for those who don't have a working configuration yet:

If you have an SXGA+ (1400x1050) screen, you have to use this size instead of 1024x768, and you have to set DefaultDepth to 16 to use AIGLX because of the limited graphics memory.
